Problem/Motivation

Noticed in #2212427-21: Use interface instead of class name for language manager where appropriate.:
Some things should be typehinted with ConfigurableLanguageManagerInterface not LanguageManagerInterface because they depend on functionality in the ConfigurableLanguageManager that comes with the language module.

Proposed resolution

typehint with ConfigurableLanguageManagerInterface (not LanguageManagerInterface) in ... ?

Remaining tasks

User interface changes

No.

API changes

Yes.

ConfigurableLanguageManagerInterface? i think all of these depend on functionality in the ConfigurableLanguageManager that comes with the language module.

Only classes in Locale + Language module can depend on ConfigurableLanguageManager, because it only exists when Language module is enabled.

Any other code can only depend on the non-configurable LanguageManager.

The comment in #2 has answered this such that I think this is working correctly.

I trust that someone will re-open this if that is incorrect.
